CARP VIP not reachable

surfdude

You're right, vlan1 of course. tcpdump -i vlan1 -n vrrp doesn't show anything.

I am not sure this is the problem but anyway - why vlan1 and vlan2 have different VlanIDs on these boxes?
And if carp works you should see VRRP packets in your tcpdumps generated by master. Try tracing other vlans.

surfdude

Ok, the vlans have now the same order on both boxes (see above). But no effect.

tcpdump -i vlan0 -n vrrp

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

tcpdump -i vlan1 -n vrrp

[nothing]

Eugene

tcpdump -i vlan1 -n vrrp on both boxes give nothing?
what about
tcpdump -i vlan2 -n vrrp

surfdude

Yes, nothing on both. vlan2 is also nothing, but thats the SYNC interface

Eugene

it's very very wird. Can you post

everything seems to be ok. If we forget about vip for the moment… can you ping real IP?

surfdude

Now i'm getting crazy. I ran a ping for a few minutes and did add a new VIP for testing. While pressing the pfsense "Apply Changes" button, this happens:

ping 192.168.51.3

PING 192.168.51.3 (192.168.51.3): 56 data bytes

round-trip min/avg/max/stddev = 0.101/0.146/0.191/0.045 ms

after this two packets, now its silence again. I can ping the real ip.

Thank you for hour help!

Eugene

may be stupid question but you have rule allowing icmp to this ip, right?
pfctl -sr | grep vlan1

surfdude

I hope so!

Eugene

Ok, sounds interesting. Can you please run tcpdump -i vlan1 -n vrrp on pfsense1 and click edit any vip and then save apply on pfsense1?

surfdude

Still nothing.

But, if I execute this command on pfsense2, I get sometimes a packet:

/sbin/ifconfig carp1 192.168.51.3/24 vhid 8 advskew 100 pass test

Eugene

i think I run out of ideas… Your carp does not work.

pfsctl -sr | grep carp
Try swap nics fxp0 and fxp1.
Sorry

surfdude

pfctl -sr | grep carp

Isn't here something wrong?

Eugene

you have this: pass quick proto carp all keep state
It means at least carp packets (vrrp) shouldn't have any restrictions.
you should have the same (almost) dump on vlan1 as you have on WAN for vrrp.
